BASIN-COCK.

Specification of Letters Patent,

Patented Jan. 9, 1906.

Application filed May 29, 1905. Serial No. 262,908.

T0 at whom it may concern:

Be it known that I, PHILIP MUELLER, of the city of Decatur, county ofMacon, and State of Illinois, have invented certain new and usefulImprovements in Basin-Cocks, of which the following is a specification.

The object of this invention is to facilitate the attachment ofbasin-cocks to slabs with the nozzles or spouts presented in proper direction, and the invention is applicable to slabs of all kinds havingholes of all shapes.

The invention is exemplified in the structure hereinafter described, andit is defined in the appended claims.

In the drawings forming part of this specification, Figure 1 is anelevation of a cock secured to a slab by means of my improvement. Fig. 2is a diagram of the securing washer looking downward from the sectionalline X in Fig. 1. Figs, 3 and 4 are details of modifications of theinvention.

The base of a cock is shown at 1, the part of the cock that extendsthrough the slab is shown at 2, and the threaded end below the slab isshown at 5. The extension 2 is pro vided with a longitudinal externalrib 3 and the washer 4 is grooved internally to conform to the rib. Thewasher is ribbed, fluted, corrugated, or roughened on the surface thatcontacts with the sides of the hole through the slab, and the externalsurface of the washer may be varied to suit different requirements. InFig. 1 the washer is in the form of a frustum of a cone, in Fig. 3 theform is that of an inverted frustum of a cone with the bearing-surfacedepressed and corrugated, and in Fig. 4 the bearing-surface is flat. Anut 6 is screwed onto the threaded end 5 of the cock extension, and itis used to force the Washer into contact with the slab. A rubber gasket7 is preferably inserted between the slab and the base of the cock. InFigs. 1 and A the slab 8 is supposed to be made of marble. In Fig. 3 theslabis assumed to be made of iron with porcelain finish, and the metalsurrounding the hole through slab 8 projects downward in the form of aboss. In Fig. 3 the Washer is given the reference-numeral 4 and themodified washer in Fig. 4 is designated by referencenumeral 4 Inattaching the cock to a slab the nut and washer are removed, theextension is inserted through the hole in the slab, the washer isslipped up onto the extension 2 and into contact with the under side ofthe slab, and the nut 6 is screwed up against the washer with su'Hicientforce to cause the ribs, corrugations, or salient parts of thebearing-surface of the washer to become somewhat embedded into thesurface of the slab. The holes through slabs are never preciselyaccurate. They are usually square, and when a circular form isapproached the circularity is never perfect. Consequently the salientparts of the bearing-surface of the washer will ordinarily finddepressions suflicient to preclude rotation of the washer when the nutis tightened; but in any event the washer may be forced into contactwith the slab with sufficient force to make a firm non-rotativeconnection and the rib 3 will hold the cock against turning in thewasher. The rib 3 prevents rotation of the washer on extension 2,whilepermitting free longitudinal motion of the washer on the extension, andthis is the desired condition regardless of the specific constructionemployed. The extension 2 may be square in cross-section or any otherform except circular, and the rib 3 is intended to be typical ofnon-circularity in the extension.

IVhat I claim as new, and desire to secure by,Letters Patent, is

1. In a basin-cock, a base to sit on the slab, a longitudinally-ribbedextension to pass through the hole of the slab, a threaded end of theribbed extension, a washer conforming to the ribbed extension and havinga corrugated or roughened bearing-surface, and a nut for the theaded endof the extension.

2. In a basin-cock, a base to sit on the slab, a longitudinally-ribbedextension to pass through the hole of the slab, a threaded end of theribbed extension, a conical, fluted washer conforming to the ribbedextension, and a nut for the threaded end of the extension.

In testimony whereof I sign my name in the presence of two subscribingWitnesses.

PHILIP MUELLER.
